Powerhouse Kjørbo in Sandvika outside of Oslo opened in April 2014 and is the first finished project of the Powerhouse collaboration. Two office buildings from the early 1980s have been refurbished, reducing their energy use by 90 percent. The solar panels on the roofs can produce more than 200 000 kWh per year – twice the amount needed to operate the buildings.
Developing a good indoor environment with low energy consumption has been a priority. Ventilation, insulation and energy-efficient lighting systems are just a few of the features that contributed to Powerhouse Kjørbo receiving a BREEAM Outstanding certification for the design phase.
